Parametric Self-Oscillation via Resonantly Enhanced Multiwave Mixing
arXiv:quant-ph/9904034 · doi:10.1103/PhysRevLett.83.4049
Abstract
We demonstrate an efficient nonlinear process in which Stokes and anti-Stokes components are generated spontaneously in a Raman-like, near resonant media driven by low power counter-propagating fields. Oscillation of this kind does not require optical cavity and can be viewed as a spontaneous formation of atomic coherence grating.
